. The invention relates more particularly to that class of brake beam supporting means,

commonly termed third point supports or fourth point supports, examples of such type of supports being illustrated in Patent No.

ctguide brakebeams by means of inclined spring tracks, between which and the brake beams are interposed shoes or carriers that travelupon such tracks. In some instances, the shoes or carriers are secured to the tracks in such manner that while being freely movable lengthwise thereof, the danger of their becoming displaced from the tracks is avoided; In practice, it is found that the brake beams by reason of their connections have a. i a tendency to move lengthwise of the beam, this movement usually being from three-fourths the normalpath of movement of the beams along the tracks in the operation of applying and releasing Recognizing this tendency of the brake beams to move in endwise direction, it is the practice in some instances to provide the upper portions of the shoes or carriers that travel upon the spring tracks with open 3 seats that will allow for the endwise play or movement of the tension members therein. In practice, it is found'that there is a tendency, under the strains and stresses to which cars, and particularly freight cars, are sub- I jected, for the tension members or portions of the brake beams to be thrown out of the open seats of the shoes or carriers.

The main object of my present invention is to provide means whereby the danger of the tension members or portions of the brake.

beams being accidentally thrown from the seats of the shoes or carriers will be avoided, while at the same time provisionis made for permitting the necessary endwise movement of the brake beams, i. e., 'afmovement transverse to the supporting spring tracks. To

this end, the invention consists in the features of novelty hereinafter, described, illustrated in vthe accompanyingdrawings, and particu larly pointed out in the claimsat-the end of this specification.

In the form of the invention illustrated in Figures 1, 2 and 3 in which is shownl'what is commonlytermed a third point support, 1 designatesthe usual spring plankof a car truck from which projectsthe usual spring track 2 having an inclined portion for sus taining and guiding the brake beam. As shown,the brake beam comprises a compressionmember 3 and tension member 4. between whichextends the strut 5.

Upon the spring track 2 is mounted the shoe or carrier 6 that is connected to both the spring track and the brake beam. As shown, the shoe or carrier 6 comprises an, expanded lower portion 7 having a slot 8 therein through which the spring track 2 vertical section on,

view showing a modified vertical section on usual seam receive the tension member 4 of the brake beam. The lug 90f the shoe or carrier projects upwardly in front of the 10 tension member 4 and the end ofthe strut 5.

o In Order tos'eoiirelyfretain thetension meinupper portion of the shoe or carrier, the lugs 9, 10 and ll are made ofnsuch length-and of 1 such material '(preferably'as a malleable casting or a forging) that when theparjts areassembled the upper end of th'elug 9 may be I bent (from the vertical position shown by dotted' lines, Figure 2)", overthe tension memmaster 4'; and the upper ends of the lugs 1 and 11 m be'bent o(;frointhefposition shown by dotted lines,*Figure 2) down upon-' the jtopgoi" the strut 5, so thatalldangerof the shoe: or

carrier becoming disengaged fremthe brake 7 2 i beam"will'bepreventedj In order to allow w for the endwise niovelnent'of the brake beam I with respect to the'track2', the slot 8 through 'which this track passesjismade very much broader than 'the'track'; that-is to say, there is a clearance between'the side edge's oflthe track? and the'end's of theslot 8iat eachside vof the track of approximately three fourths of an inchQ-j P 5 y i j to m offthe inventionillustra-ted in 351 Figures'4, 5 and Gofthe drawings, the lower portion 7 of the'shoe' or carrier is shown as I formed with a slot 8"that is'butslightly wider than the 'width'of' the "track 2.; .With this form of the, invention, in ord'erit'o allow for 4olitlie endwise movementfofthe brake beam,'the upperportion of the shoeor carrier'is formed withupstanding' end wallsand withlugs 9?, 10% and 11, theupper ends of which lugsare adapted to-jbe bent downwardly and inwardly a suflicient distance tozretain theshoe, or carrier in'position'upon the brake beam, while at the same time allowing a free" endwise movement of the brake beam to a' suflicient extent (saypabout three-fourthsof an inch) fi infea'ch "direction 'In order to permit this free endwise'movementof the brake beam, it

will benoti'ced thatthe upstanding end walls of 'theshoeforcarrier' are so. wide apart that" there will be a clearance of about three-' 65, fourthsof an} inch betweenithe sides of the strut 5" and theend 'wallsi and it will beno ticed'also that there is sufiicient space between 'the'bentover,lugs1 9f 10% and ll rto allow free lateral movement of-theparts.

f D ,Intheiform of the invention shown in' Figmes 7 and. 8', the 5 construction of the" lower 7 part sho'eor carrier'is similar to that illustratedinEigures4, 5 and- 6 that s to say ,-':the; shoe or carrier has a: lower portion 17? withatffiarrow sIQt- S ftherein, through As shown, the upper portion of the which passes the spring track 2. I In this iorni of the invention, there are vertical lugs or side members 14 and'15 rising from the shoe or carrier at the sides of the strut 5, and

there is 'a vertical lug or end member 16 opposi te the outer end ofthe strut 5. V The'lugs or slde members 14 and 15' are spacedat a suilioient distance apart to permit the free endwise or lateralmovementof the brake beam, hereinbefore referred to,'iand the lug or end member 16 is at a distance from the her 4 and the end ofthe strut 5 withinthea free end of the strut 5' so as not to interfere with such lateral movementiof the brake beam. In order to retain. the tension portion of the l5 arejpreferablybifurcated and perforated,

as shown, to receivethe' ends of the locking.

guard bar 17, and to receive suitable pins, rivets or the like to hold the bar 17in engagement with theflugs 14 and l5. As'shown, one end 01": the guard bar 17 is pivotally connected to alug 14 by a rivet '18 so that the guard bar can be swung fromthe position shown in dotted lines to the positionshown in 'full lines in Figure'7, and when in the closed position shown "by run lines in Figure 7, the guard bar 17 can be held in place by a suitable rivet, bolt'or pin 19;

In the form of the invention illustrated in Figures 9, 10 and 11, my invention is shown as applied to what is commonly *termed1a fourth point support for, brake beams; In this embodiment of the invention, there will be supportingspring track 2 at each side of the center ofthe brake beami- One only of such tracks and the shoes or carrier thereon is 'illustrated in' the drawings, as it'will beaunderstoodmth'at a similar track and shoe: will i be provided at the opposite side of the I brake beamstrut 5. In this form of the in 'vention, the lower portion-7 of the shoe or carrier is provided with a comparatively nare row slot throughwhich thespringtrack 2 passes, this slot being otproper dimension to permit the shoe'or carrier to moveclongi-v tudinally of the track. JAs shown, thetop of the shoe or carrier: is formed withupstanding flanges 20 and 21 arranged-diagonally with respectto the ends'of the shoe or carrier, and at sufficientdistance anart'to admit the tensionmember ofthe' brake beam and allow it to move transversely between the flangesiQO and 21;] S o,ialso the top; of the shoe or carrier is formed with lugs 22 fand'23 adapted to be bentdown and, in

wardly,' as shown," in order t'o prevent all danger of the tension member 4 becoming accidentally disengaged; from .the' shoe 'or' carrier under thejars and strains tojwhich the parts in'practic'e are subjected. hen the parts are assembled, as shown in Fig ures 9, 10 and 11, the tension member 4 may have a free endwise movement with respect to the shoe or carrier.

In the form of the invention shown in Figures 12, 13 and 14, the construction of the shoe or carrier is the same as that illustrated in Figures 9, 10 and 11, except that the lugs 22 and 23 are formed as vertical lugs, with holes in their upper ends adapted to receive a cotter pin 25 that will extend between the lugs 22 and 23 and will serve to prevent the accidental disengagement of the tension member 4 from the shoe or carrier.

While I have described what I regard as the preferred embodiments of my invention, it will be understood that the details of construction may be varied widely and that features of the invention may be employed without its adoption as an entirety.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A brake beam support, comprising the combination with a brake beam of a supporting track, a shoe arranged between the tension member of the brake beam and the track, said shoe having a lower portion provided with a slot materially wider than the track for retaining it in engagement with the track while permitting a free transverse movement of the shoe with respect to the track, and

having on top of said lower portion a seat to receive the tension member of the brake beam, and means for engaging said tension member comprising bendable means integral with said shoe and adapted to retain the shoe on the tension member on both forward and backwardmovement thereof and to prevent the lifting of the tension member from engagement with the shoe.
